No company makes good after market cylinders for the quad racers? I know port work makes a huge difference but there's only so much a stock cylinder (and even a stroker crank) can do. From my experience 45rwhp is way more than enough on four wheels. Especially for two strokes, traction is very hard to obtain but I ride on grass a lot.
As for needing more power. I had more fun when my bike was bolt ons. She's a little rowdy these days.
